Leveling screw yoke

[Clear Fork Ed]

The part number for both leveling screw yokes on my 1957 620 is F 2670 R does that indicate that they are both right-handed threads? I realize that this may be like asking who is buried in Grant's tomb but the right leveling screw is stamped with an R and the left screw mark is covered by the yoke. Thanks ! Ed

The three point leveling screws on my 630
and my 620 are all right hand thread.

Re-reading your question - no, I don't think that the R in the part number has anything to do with the thread cut.

R means it is a Waterloo part number. H
is harvester works. E is Ottumwa works.
